Selling your own belongings on eBay — old tech, clothes, the loft clear-out — is not taxable, whatever it fetches. Tax starts when you're trading: buying stock to resell, flipping items for profit, or making things to sell. Traders get a £1,000 trading allowance per year across all platforms combined; above that you register for Self Assessment and pay Income Tax on the profit (plus Class 4 NI once profit alone passes £12,570). The calculator above is for traders.
- Decluttering ≠ trading. Personal possessions sold second-hand — usually at a loss — create no Income Tax, regardless of volume or value.
- Buying to resell = trading from the first flip. Over £1,000 of gross trading income a year means registering for Self Assessment by 5 October 2027.
- eBay must report sellers to HMRC at roughly 30 sales or ~£1,700 a year — a reporting rule, not a tax bill.
- Registering as an eBay business seller is how you tell eBay you're trading — HMRC applies its own "badges of trade" test either way.
- A single personal item selling for over £6,000 (jewellery, art, watches — not cars) can trigger Capital Gains Tax instead.
Do I pay tax on eBay sales?
HMRC looks at why you acquired what you're selling. Bought it for yourself, used it, selling it on? Not trading. Bought it at a car-boot sale on Saturday specifically to list on Sunday? Trading. The "badges of trade" include buying with intent to resell, short ownership, frequent repeated sales, commercial quantities, and improving items to sell — the more badges, the more clearly you're a trader. Volume alone proves nothing: 100 sales from a genuine house clearance is still not trading.
Private seller vs business seller
eBay's account types matter for eBay's rules (private sellers currently pay no final-value fees on most UK listings; business sellers get VAT invoices and consumer-law obligations), but they don't decide your tax position — HMRC's trading test does. That said, running trading-level volume through a private account is a classic nudge-letter trigger once eBay's reports land at HMRC: the account label and the activity should tell the same story.
Worked example — part-time reseller
| Step | Calculation | Amount |
|---|---|---|
| eBay sales (bought to resell) | the year's gross sales | £6,000 |
| Stock, postage, packaging, fees | actual costs | −£2,600 |
| Actual expenses beat £1,000 allowance | £2,600 > £1,000 | — |
| Taxable profit | £6,000 − £2,600 | £3,400 |
| Income Tax (basic-rate employee) | £3,400 × 20% | £680 |
| Class 4 NI | profit under £12,570 on its own | £0 |
| Owed via Self Assessment (31 Jan 2028) | £680 |
With a day job, enter your salary in the "other income" box above — profit is taxed at your highest rate, so a higher-rate taxpayer sets aside 40p in the pound rather than 20p.
Frequently asked questions
eBay asked for my National Insurance number — am I in trouble?
No. Platforms must collect seller details and report anyone passing roughly 30 sales or €2,000 (~£1,700) a year to HMRC. It's routine data-sharing: HMRC cross-checks reports against tax returns. Declutterers have nothing to do; unregistered traders should register before HMRC's nudge letter arrives. Full detail in the platform-reporting guide.
I sold over £1,000 of my own belongings — do I need to report it?
No. The £1,000 trading allowance only concerns trading income. Selling personal possessions isn't trading, so the threshold doesn't apply — £5,000 from clearing out your garage needs no return.
Which expenses can eBay traders claim?
The cost of stock, postage and packaging, eBay and payment fees on business sales, mileage for sourcing and posting (55p a mile), a proportion of phone and internet, and storage costs. Or skip itemising and deduct the flat £1,000 trading allowance if your real costs are lower — the calculator compares both.
Do the same rules cover Vinted, Depop, Etsy and Facebook Marketplace?
Yes — one trading test, one £1,000 allowance shared across every platform combined, and the same reporting thresholds on each. If you trade on three platforms, add the income together before comparing against £1,000. See the Vinted calculator for the clothes-selling specifics.
When does reselling need a VAT registration?
Only once taxable turnover passes £90,000 in a rolling 12 months — far beyond most side-hustle resellers. If you're anywhere near that, you've outgrown this page: see the VAT calculator and get an accountant.
